PowerEdge MX7000 Acoustical Baffle

SUMMARY
For highly-sensitive noise
environments, the new
PowerEdge MX7000 offers an
optional Acoustical Baffle.
Users have commented that the
baffle improved sound quality “to
a kind of white noise”.
Installation of the MX7000
Acoustical Baffle can be
performed quickly in the field, no
tools required.
Modular systems can be loud: The power, density, scalability and dynamic
range of rack-mounted modular systems (such as PowerEdge blade enclosures
and PowerEdge FX2) requires a powerful cooling capability that can generate
more acoustical energy than a traditional rack-mount server. Customers that
choose the scalability and flexibility of a modular platform often sacrifice noise
sensitivity in the process and are left with few choices when it comes to
mitigating the increased noise associated with these products. In the 14th-
generation of PowerEdge servers, Dell EMC has embraced this acoustical
challenge and worked with a jury of IT professionals to develop several
solutions for customers to reduce the noise impact of modular systems One of
these solutions is the MX7000 Acoustical Baffle.

The acoustical baffle is an optional, simple-to-install add-on that snaps to the
rear of the MX7000 chassis directly behind the rear fans. When installed, the
baffle improves the acoustical output of the rear fans and diffuses some of the
airflow away from someone working behind the chassis. The acoustical baffle
is specifically designed for noise-sensitive deployments that may require
temporary or permanent noise mitigation. IT professionals surveyed on the
performance of the baffle reported that it improved sound quality “to a kind of
white noise”, and that it “removed shrill tones by muffling the higher
frequencies”. Most importantly, when the baffle is deployed in conjunction with
the Sound Cap profile in iDRAC, noise levels typically remain low enough to
carry on a conversation within a meter of the chassis.

2. MX7000 Acoustical Baffle installation instructions
Installation of the MX7000 Acoustical Baffle is simple and straightforward:
1. Access the rear of an MX7000 chassis.
2. Align the acoustical baffle with arms facing (inwards) toward the rear of the chassis and optical window on the
bottom.
3. Locate the cut outs on each side of the rear of the chassis.
4. Push the baffle until the tabs engage onto the chassis.

MX7000 Acoustical Baffle restrictions
 Although the geometry of the MX7000 Acoustical Baffle is optimized to minimize any impact to the cooling
capability of the rear fans, the baffle is not recommended for systems configured with CPU’s that have TDP
specifications greater than 140W1 operating in environments warmer than 35°C. In these situations, system
performance may be impacted.
 The acoustical baffle is not designed as a cable management tool and cannot support the weight of cables.
Do not lay cables on the baffle or affix cables to the baffle.
Conclusion
For noise-sensitive deployments, the optional PowerEdge MX7000 Acoustical Baffle can be installed to mitigate
acoustical output. The acoustical baffle improves sound quality “to a kind of white noise”, as users have commented.
Users comfortable with Data Center levels of noise need not install the optional acoustical baffle, but where quiet
operation is paramount, the MX7000 Acoustical Baffle is highly effective.
Notes:
1. Performance of some low core-count processors with TDPs below 140W may also be impacted by the presence of the baffle in higher
ambient environments. Reach out to your Dell representative for more information.
